Abstract: Forming device comprises e.g.: at least one base plate (1), on which a multiple number of rods (2) are vertically arranged along a longitudinal direction of the base plate; a multiple of lower fiber guiding devices (3), which are arranged on the rods adjacent to the base plate, and upper fiber guiding devices (4) arranged on the rods and are spaced apart from the lower fiber guiding device, where the rods are retractable into the base plate; at least two half shells (6) arrangeable on the base plate, form a mold corresponding to an outer contour of the fiber composite component-hollow-profile. Forming device for fiber-semi-finished- and fiber composite component-hollow profiles, comprises (a) at least one base plate (1), on which a multiple number of rods (2) are vertically arranged along a longitudinal direction of the base plate, (b) a multiple of lower fiber guiding devices (3), which are arranged on the rods adjacent to the base plate, and upper fiber guiding devices (4) arranged on the rods and are spaced apart from the lower fiber guiding device, where the rods are retractable into the base plate, (c) at least two half shells (6) arrangeable on the base plate, which form a mold corresponding to an outer contour of the fiber composite component-hollow-profile, where the half shells are releasably engageable at least with the upper fiber guiding devices, (d) recesses provided at least on one end form a passage opening of the mold corresponding to an internal cross-section of the hollow profiles on the front sides of the half shells, and (e) a core mold. Independent claims are also included for: (1) a manufacturing device for manufacturing the fiber semi-finished-hollow profiles made of continuous fibers and for preparing the continuous fiber composite component-hollow profiles made of the fiber semi-finished-hollow-sections, comprising a movably guided fiber supplying unit, at least one above mentioned forming device and a matrix infiltration device; and (2) manufacturing the fiber composite component-hollow profiles using the above mentioned manufacturing device, comprising (a1) providing the forming device for the fiber composite component-hollow profiles, positioning and fixing the lower guiding devices on the rods adjacent to the base plate, from which the rods extend, arranging and fixing the upper guiding devices on the rods, which are spaced apart from the lower guiding devices, (a2) supplying a continuous fiber by the fiber supplying unit and placing the continuous fibers along a laying path, where the laying path comprises a sub-floor path extending rectilinearly and/or alternately below the lower guiding devices, an upper path that extends rectilinearly and/or alternately along the upper guiding devices and bypaths, which extend on one side between the upper guiding devices and the lower guiding devices, to obtain the fiber semifinished-hollow profile, (a3) arranging the half-shells on the base plate around the continuous fibers deposited on the guide means and forming the formwork, engaging the half shells with at least the upper guiding devices, (a4) introducing the core mold through the passage opening of the front side of the formwork up to a first rod, (a5) successively lowering the rods into the base plate and readjusting the core mold until the core mold exits from the passage opening of a second front side, (a6) infiltrating the fiber semi-finished hollow profile with a matrix material and hardening, and (a7) removing the half-shells, the core mold and the guiding devices, and obtaining the fiber composite component-hollow profile.
